1. The fire stations at the Tunstall
end of the base.Paul Topolosky adds: "The shelter in your photos next to the fire department was
used for liquid oxygen and liquid nitrogen tank storage. When I realized
the photo was of the shelter next to the fire department it jogged my
memory a bit more. The one photographed and one at Woodbridge just before
you enter the fuels storage area, on the right hand side of the road,
were used for the oxygen and nitrogen."

2. A hardened refuelling truck shelter (David Galvan). Several
of these around the base.
More details from Curtis Osier: "This
Bldg. is a POL (Fuels) Truck Shelter with 2 foot thick cement walls and
1 foot thick steel doors. It would have contained 2 R-5 or R-9 trucks
- refueling units - both held 5,000 gallons of jet fuel. The reason I
recognised the building is because I helped paint it in 89."

Even more info
from Gary Keefer: "The
structure in picture #2 (in the background with brown top) and the structure
in picture #3 are aircraft refueling truck hardened shelters. Note the
fuel vapor ventilation fan on the roof. Gary Keefer, MSgt, USAF"

Yet more information,
from Paul Topolosky; "We
used these buildings to store our refuel trucks. We had to store a certain
number of refuelers in what was called War Reserve Material (WRM). During
exercises we would park the refuelers we used in those buildings to hide
them from the enemy and protect them from attack. We called the buildings
"Truck Shelters". We would back the trucks into the shelter, open the
small square door in the back, close and lock the four large doors, and
enter the shelter from the small door we had previously opened and lock
ourselves in from the inside. When needed to refuel the aircraft we would
receive a call on the radio. That was one of the favorite places to spend
the day for us fuel truck operators during exercises because once locked
inside we would not wear our gas masks like the rest of the base because
the inspectors could not get in to see us. We would have to let them in
so we would only wear our masks when they knocked on the door to get in." But this actual truck store is something else (see Paul's comments about
that particular building).
